LONDON, England (CNN) -- The pressure on FIA president Max Mosley is mounting after four car manufacturers released statements expressing their disappointment following allegations he was involved in a sex scandal.

FIA president Max Mosley faces more pressure to resign after revelations about his sex life were published.

BMW and Mercedes Benz described the content of the story, published by the UK's News of the World tabloid, as "disgraceful."

Toyota and Honda also released statements expressing their concern.

On Sunday, the newspaper ran an expose on Mosley alleging he took part in an orgy with Nazi overtones.

The 67-year-old Mosley rejected calls to step down, writing a letter to FIA officials saying he was embarrassed by what the newspaper reported but said there was no "Nazi connotation to the matter".

A video, posted Sunday on the newspaper's Web site, showed a man identified as Mosley arriving at an apartment and then engaging in various sex acts with several women, at least one in a prisoner's uniform, while also speaking German. The video can no longer be found on the Web site.

BMW and Mercedes Benz said they "strongly distance ourselves from it [the story]."

"This incident concerns Max Mosley both personally and as president of the FIA. Its consequences therefore extend far beyond the motor sport industry."

Toyota released its own statement, saying it "did not approve of any behaviour which could be seen to damage Formula One's image."

"Senior figures within any sport or business, including motorsport, must adhere to high standards of behaviour," Toyota said.

"When all the facts are known, it will be for the FIA to decide whether Mr Mosley has met the moral obligations which come with the position of FIA president."

Honda, meanwhile, said it was "extremely disappointed" by the recent events surrounding Mosley.

"We are concerned that the reputation of Formula One and all its participants is being damaged. We request that the FIA gives this matter careful consideration and reaches an immediate decision in the best interests of F1 and motorsport."E-mail to a friend
